As someone who relies alot on lineart, I find drawing video game characters incredibly frustrating sometimes. Having to lineart art every small detail of a characters outfit makes my head explode.🫠

The voices in my head always tell me that i shouldn't do a second sketch and go straight into the lineart. This shit never goes well for me, yet i do it anyway. I want to beat my own head with hammers.

Does your artwork ever feel a little flat? Simply adding more variation to your line weight can instantly make your illustrations feel more dynamic and polished! ✨ Check out these tips and take your lineart to the next level!

Linear actuators playing football! ⚽️ You can keep scrolling... The "Magic Field" is an impressive display of ball-handling skill, showcasing what fixed automation can achieve. There are no robots at all. Instead of robots, over 300 linear actuators precisely control the ball’s movement on the field, demonstrating incredible accuracy. The setup even includes an advanced kicking mechanism, similar to a SCARA robot, that uses two linear actuators and one rotary actuator to kick the ball into the net. 🥅 This fixed automation shows how powerful and precise automation can be without needing mobile robots on the field. ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

"Linear time is an illusion." Elif Shafak on why our sense of time and reality is wrong: "There is magic in life, in daily life, in even the most ordinary, seemingly ordinary moments. That's one of the reasons why I don't like this term magical realism, because it assumes that there is the world of magic and then there is the world of reality. Whereas I think in life everything is constantly mixed." "We want to think of time as a much more linear, steady march. But when you pay attention to a river, a tree, a rock, just the soil itself, there is no linear time there."

A linear equation, first-order in time, that determines the entire future of an isolated quantum system from the present values of its wave function. iħ ∂Ψ/∂t = ĤΨ The same operator Ĥ that generates the motion is the observable whose eigenvalues are the energies a measurement can return. Schrödinger obtained the equation in 1926. When the potential does not depend on time the solutions of definite energy separate as ψ(x) e^{-iEt/ħ}, leaving the eigenvalue problem Ĥψ = Eψ whose Coulomb eigenfunctions reproduce the discrete spectrum of hydrogen.
